The functions and uses of casing pipe?

Casing pipe is an indispensable equipment in oil drilling and plays an important role.Casing pipe is a steel pipe that supports the walls of oil and gas wells. Each well uses several layers of casing based on different drilling depths and geological conditions. Cement must be used to cement the casing after it is lowered into the well. Unlike oil pipes and drill pipes, it cannot be reused and is a one-time consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes. According to the usage, casing can be divided into: conduit, surface casing, technical casing and oil layer casing, and their structure in the oil well.

Analysis of causes of oil well casing end cracking

CO2/H2S corrosion is a common corrosion type in the oil and gas industry. With the development of oil and gas fields such as CO2-containing deep wells and ultra-deep wells, the emergence of H2S-containing corrosive gases has made the service environment faced by downhole oil casings more demanding and complex.
